I want to share a script for an Youtube player that can be used to see videos in sync with your friends in your domain. To use this script, create an entity primitive box, size it to have a proportion aprrox. 16:9 between width and high (like a tv screen) and place this script on script URL:

http://transmissiongate.com/youtube.js

A 3D web entity overlay will be rezzed on this box. In the left bottom corner you have a paste video link. Here you can place video links and press Enter.
